DIAPHANOUS PICTURE.

SPECIFICATION forming part of Letters Patent No. 594,655, dated November30, 1897.

Application filed May 26, 1897- Serial No. 638,214. (No model.)

To all whom it may concern:

Be it known that LWILLIAM SOHUMACHER, a citizen of the United States,residing in the city of Boston, in the county of Suffolk, in the Stateof Massachusetts, have invented certain new and useful Improvements inDiaphanous Pictures, of which the following is a specfication.

This invention relates to diaphanous pictu res which are made insuitable colors on paper, textile fabrics, and other substances, so thata clear and uniform appearance of the picture from either side of thesheet is produced.

The invention consists of a diaphanous picture printed by print andcounter-print in register on both sides of the sheet and having similarvarnish impressions applied to said colors in register with the same andwith each other, as will be hereinafter fully described and thenclaimed.

In the accompanying drawings, Figure 1' represents a front view; Fig. 2,a vertical transverse section of my improved diaphanous pictures, andFig. 3 a rear view.

Similar letters of reference indicate corresponding parts.

In carrying out my improved invention a sheet of paper, fabric, or othermaterial to receive the impressions in colors is fed to a lithographicor other printing press, which is provided with a backer of rubber orother elastic material. This backer is held in the wellknown manner infixed position, so that it will return exactly to the same position atevery revolution of the press. The printing block or plate is nowcharged with ink in the usual manner and an impression delivereddirectly on the backer. After this the printing block or plate ischarged with ink again and the sheet fed into the press, so that thecolors are applied simultaneously in print and counterprint to bothsides of the sheet, the sheet receiving simultaneously the impressionsfrom the printing block or plate and from the backer. The impressionsmade by print and counter-print are in perfect register with each other,which is accomplished as the backer is firmly held in its properposition. The entire edition to be printed is thus run through theprinting-press and two impressions given to the sheet on one side by theprinting block or plate and on the other side by the hacker. When thepicture is to have a number of colors, one color after the other isprinted in the 5 5 same manner. After the colors are printed andproperly registered at the opposite sides of the sheet the picture ismade transparent or diaphanous by supplying varnish instead of ink toboth sides of the sheet in the same manner as before described withcolors, the varnish rendering the parts of the picture to which it isapplied at the front and back of the sheet transparent, while theremaining part of the sheet retains its semiopaque or opaque ground. Thevarnish prints and reprints can'also be made before the colors areprinted. Any desired transparent effect can be produced by making theplate instead of solid in tint effects in the same manner as they areproduced on stone or other printingplates. Besides whenever the coloredpicture is printed opaque the first or final application of varnish willproduce half or quarter transparent effects, according to the nature ofthe plate made for this purpose.

I do not claim the printing of colored pic-. tures in register with eachother at both sides of the sheet, as this has been done heretofore, butI desire to claim the producing of the diaphanous effect of such apicture by applying an impression of varnish by print and counter-printon the sheet before or after it is printed on both sides, so as toproduce atransparent or diaphanous picture.

When a picture in uniform color and tint is required, a solid plate isused and full transparency produced by the varnish impressions. Whenevera half or quarter is to be produced,

the corresponding tints are produced on the 0 I plate by which thevarnishimpressions are made, so that the sheet is printed in acorresponding manner with the varnish impression on both sides, so thatcorresponding transparent effects are produced and brilliant- 5 light,half-light, and middle-light effects are obtained.

Having thus described my invention, I

In testimony that I claim the foregoing as my invention I have signed myname in presence of two subscribing witnesses.
